Short summary
Multiple year-round records of bulk and size-segregated composition of sea-salt aerosol and acidic gases (HCl and HNO3) were obtained at inland Antarctica. Both acidic sulfur particles and nitric acid are involved in the observed sea-salt dechlorination in spring/summer. The observed sulfate to sodium mass ratio of sea-salt aerosol in winter (0.16 ± 0.05) suggests on average a similar contribution of sea-ice and open-ocean emissions to the sea-salt load over inland Antarctica at that season.
